The $25 DIY Bike Stand constructed last month has proven to be a very worthwhile project. I love this thing, since building it I am constantly finding excuses to use it. Be it periodic inspections, maintenance, cleaning, or just to stare at the bike. While functional, the PVC stand is still not perfect. Drawing from a little hands on time and the lessons learned from the original build, I worked out some improvements.
The threaded union was added to allow the clamp to rotate into multiple positions. Unfortunately, no matter how much the union was tightened, it did not have enough friction to prevent rotation of the clamp on a suspended bike. The union consists of two pieces of PVC pipe that screw together with an o-ring in between them. The O-ring is designed to form a seal , and limit the rotation between the two pipes in the joint. While it is sufficient for plumbing, it is by no means adequate for holding a bike.
